You can just chat through the Vitas party app, you don't even need to be playing the same game. Resistance was just a trial run for COD - made by the same developers. It's not very good. Anyway by the time you guys get a vita killzone will probably be out and that game is running on the Killzone 3 engine.......do I need to say more? Anyway how did this topic turn into a ps vita discussion?
